Abstract
Pyrazoline dye has been synthesised from diazonium salt of 4-amino- 2,3-diamino-1-phenyl-3-pyrazoline-5-one by coupling with 2,7-hydroxy naphthalene. Azo dyes are characterised by the presence of one or more azo (–N=N–) groups. This class of dye is well known for dyeing potentialities and biological activities. The fastness of azo dyes varies widely with structure and environment.
